汉译英：注意力UNet使用注意力门模块来突出图像的重要相关特征并抑制不相关的特征。在该模型中硬注意力被软注意力取代注意力模块被集成到UNet网络的跳接和上采样模块中以实现空间注意力机制

The UNet model uses attention gate modules to highlight important and relevant features in images while suppressing irrelevant ones. In this model, hard attention is replaced by soft attention, and the attention module is integrated into the skip connections and upsampling modules of the UNet network to implement spatial attention mechanisms.
